In 2003, the new Rolls-Royce Phantom car reintroduced independent rear-hinged doors in luxury vehicle applications. Other luxury models with rear-hinged doors include the Spyker D8 and the Rolls-Royce Phantom Drophead Coupe four-seat convertible. The most recent mass-produced model with such doors may be the Opel Meriva, followed by the Rolls-Royce Cullinan in 2018, and a few Chinese electric vehicles including the Singulato iS6 in 2018 and HiPhi X in 2020. Lincoln announced that 80 limited-edition 2019 Continentals would be made with "coach" doors, marking the Continental's 80th anniversary. The 2020 Citroen Ami electric vehicle is unusual in having a suicide door for the driver but a conventional door for the passenger, as the doors are identical units that are not differentiated by side. At the end of the 20th century, companies experimented with doors: rear-hinged rear doors that are held closed by the front doors, and cannot be opened until released by opening the front door on the same side (hinged at the front). Such doors may be referred to as clamshell doors. Porsche created a prototype in the late 1980s based on the 928 "Study H50". In the 90s, concepts with such doors were released - 1990 Pontiac Sunfire, 1997 Pontiac Rageous and Mercury MC4. In the early 2000s, have appeared on a number of vehicles. Examples include extended-cab pickup trucks, the Saturn SC, Saturn Ion Quad Coupe, Honda Element, Toyota FJ Cruiser, BMW i3, Mini Cooper Clubman, Mazda RX-8, Mazda MX-30 Several concept cars have featured rear-hinged doors, such as the Lincoln C, a hatchback with no B-pillar and rear-hinged doors at the rear, or the Carbon Motors Corporation E7, a police car with rear rear-hinged doors designed to aid officers getting handcuffed passengers in and out of the back seat. The Kia Naimo, an electric concept car, also has rear suicide doors.

Note that there is no B-pillar and therefore there are two pillars, A and C. ==Advantages==

Rear-hinged doors make entering and exiting a vehicle easier, allowing a passenger to enter by turning to sit and exit by stepping forward and out. This is important for passengers who need to make a dignified entrance; the UK State Bentley has rear-opening passenger doors that are broader than usual and open very wide, allowing the monarch to exit the car in a dignified way. In combination with traditional front doors, rear-hinged doors allow chauffeurs easier access to the rear door. In Austin FX4 taxis, drivers were able to reach the rear exterior door handle through the driver's window without getting out of the vehicle. Rear-hinged doors also allow a better position for a person installing a child seat into the back seat of a vehicle than conventional doors, while being simpler and cheaper to build than the sliding doors commonly used on minivans. The Opel Meriva B compact MPV introduced in 2010 had such doors. The combination of front-hinged front doors and rear-hinged rear doors allows for a design without the B-pillar, creating a large opening for entering and exiting the vehicle. ==Disadvantages==

LT 600 van with a front suicide door When front doors are directly adjacent to rear suicide doors, exiting and entering the vehicle can be awkward if people try to use the front and back doors at the same time. There are also a number of safety hazards: • Aerodynamic factors forcing rear-hinged doors open at speed in older cars. In 1969, Consumer Reports reported this problem on a Subaru 360. • If a person not wearing a seat belt falls out of a moving car with a coach door, the door can catch them and drag them along the road at speed, causing serious injuries. • If a person exits a vehicle while parallel parked and a car hits the door from the rear, the person would be crushed instead of the door being ripped off. Car manufacturers mitigate these hazards with such safety features as seat belts, and locks requiring front-hinged doors be open before permitting rear-hinged doors to open. ==See also==
